ROTARY MOTOR.

SPECIFICATION forming part of Letters Patent No. 777,302, dated December 13, 1904. Application iiled December 1, 19.03. Serial No. 183,400. (No model.)

T0 all 'whom it may concern.:

Be it known that I, JOHN OsvE'rIMsxY, a subject of the Emperor of Russia, residing at Favodskaya street, house Bagin, Kamishlov, Russia, haveinvented certain new and useful Improvements in Motors, of which the following is a specification.

My invention relates to a motor of special kind l propose to call ,"funnel-screw whirl, which is able to be worked by steam, gas, water, wind, and so on.

1n comparison with the motors already known and in use that forming the object of this invention is distinguished by the following advantages: First, in all modes of its operation it is not subject to counter-pressureor reaction, the driving means acting in a continuous jet on the whole extension from the inlet-opening to the outlet of the motor; second, it needs no complicated transmitting contrivance; third, it has no dead points; fourth, it develops a rather high force and is working with great speed; fifth, its working is uniform without rattling and rocking; sixth, the amount of the driving means spent being small the motor proves to be economical; seventh, no special attendance or repair is wanted; eighth, is simple in construction and not expensive, Considering all these advantages it will be easily understood that the motor has all necessary qualities to be substituted for the existing' motor-engines. 1t is specially fit for ships, vessels, boats, &c., on account of its compactness and its property to impart ahigh speed. Likewise it may be used in aerial navigation, as it affords the possibility to utilize the atmospheric currents for driving balloons and other aeronautic apparatus.

The motor substantially consists of a shaft, on which is twisted spirally a blade in the shape of a strap or band having' one of its edges fixed inclinedly to the side surface of the shaft. So a series of plain funnels is formed communicating' with each other and designed to actas receivers of the driving means, which is iirst entering into the openend funnel and subsequently passes in spiral fashion in the other funnels. By the pressure exerted by the driving means on the bandblade the shaft is brought in quick rotary motion. The speed of rotation depends upon the angle of dip of the helical blade with respect to the axis of the shaft and, further, upon the pitch of the spiral. By varying these elemlents a more or less considerable speed may be obtained.

In the accompanying drawings, Figures 1 and 2 are respectivelya side elevation, partly sectional, and a plan of the motor intended foroperating by steam. Fig. 3 represents, on enlarged scale, the steam expansion slidevalve.

As may be seen from Figs. 1 and 2, the motor or funnel-screw 1 is located in a cylindric jacket 2, secured by means of posts 3 to the main frame 4. The shaft 5 of the motor projects through the stuiiing-boxes 6 6 and is supported by bearings on the posts 7. The ends of the shaft are held `in place by pointed screws 8 8.

9 is the steam-inlet pipe, and 10the steamdischarge pipe. The pipe 9 is provided with removable box 11, in which is located the slide 12, Fig. 3. This slide-valve closes the steam-admission for a certain angle at each turn of the motor, so that the steam acts by expansion, and in consequence more economically. The slide consists of a plate having two rectangular slots 13 13, which are alternately opening and closing the corresponding holes in the slide-chest. In Fig. 3 these holes are shown half-closed. The slidevalve is secured to the hoop 14, which embraces an eccentric 15, Iixed on the shaft 5 of the funnel-screw and being' provided with a groove in which is held the hoop 14. The steam flowing from the generator through the pipe 9 runs against the blade a. of the funnelscrew and by expanding `imparts rapid rotary motion to the latter oppositely with respect to the direction of the arrow, which shows the iiux of the driving means. Then the steam escapes through the pipe 10.

. 16 is a fly-wheel.

9.2 is a trausmission-sheave,` and 23 represents supports preventing the shaft from being laterally displaced and bent through. f

The said motor may be adapted for both forward and backward motion, two funnelscrews being mounted on a common shaft and each of them surrounded by a separatejacket or casing with separate steam-inlet pipes. At each stroke of the motor the funnel-screw corresponding to the backward motion is also rotating, but does` not receive steam.

I claim as my invention In a rotary motor, the combination with a shaft 5, located in a cylindrical jacket 2, stuifing-boxes 6, through which the shaft 5 passes,

IO a single blade 1 shaped like a strip or band,

having one of its edges fixed at an angle with
